Large water reservoirs found in 'star forming' cloud

The new Herschel space observatory of European Space Agency (ESA) found that a cold pre-stellar core in the constellation of Taurus known as Lynds 1544 are the first detection of water vapour in a molecular cloud on the verge of star formation.

More than 2000 Earth oceans-worth of water vapour were detected, liberated from icy dust grains by high-energy cosmic rays passing through the cloud.

"To produce that amount of vapour, there must be a lot of water ice in the cloud, more than three million frozen Earth oceans
